ENGLISH
The electrical wiring to the external probe is made with a bipolar ca-
ble with a section from 0.5 to 1 mm
length of 30 metres. It is not necessary to respect the polarity of the
cable when connecting it to the external probe. Avoid making any
joints on this cable however; if joints are absolutely necessary, they
must be watertight and well protected.
Any ducting of the connection cable must be separated from live ca-
bles (230V AC).
FIXING THE EXTERNAL PROBE TO THE WALL
The probe must be placed on a smooth part of the wall (Fig. 4); in the
case of exposed brickwork or an uneven wall, look for the smoothest
possible area. Loosen the plastic upper protective cover by turning
it anticlockwise.
After deciding on the best fixing area of the wall, drill the holes for the
5x25 wall plug.
Insert the plug in the hole. Remove the card from its seat.
Fix the box to the wall, using the screw supplied.
Attach the bracket, then tighten the screw.
Loosen the nut of the cable grommet, then insert the probe connec-
tion cable and connect it to the electric clamp.
To make the electrical connection between the external probe and
the boiler, refer to the "Electrical wiring" chapter.
Remember to close the cable grommet well, to prevent any air
humidity getting in through the opening.
Put the card back in its seat.
Close the plastic upper protective cover by turning it clockwise. Tight-
en the cable grommet very well.
3.7 Installation of the remote control panel
To correctly check the ambient temperature, the control panel
should be installed in a reference position in the home.
For a correct installation, keep in mind that the panel:
 it should be installed on a wall, preferably not a perimeter one,
that has no hot or cold pipes running through it
 It should be fi xed about 1.5 m from the ground
 It should not be installed near doors or windows, cooking equip-
ment, radiators, fan coils or generally in conditions that might
alter the measured temperatures.
YES
SI
In order to fi x the panel to the wall, proceed as follows:

 separate the control panel from the base
 use the base as a template for marking the fi xing points on the
wall
 drill holes in the wall (ø 6 mm holes)
 fi x the base to the wall using the screws supplied
 Insert 2 type AA batteries;
